The present invention generally relates to support web based multitasking for a single computing device or a plurality of computing devices of a web based central controlled distributed scalable virtual machine system (“CCDSVM”). with respect to a web based computer user work environment.
A typical computer system provides a computer user work environment to end users, wherein the computer user work environment runs on top of a generic computer operating system. With this work environment, an end user can login to the computer system and. setup various computer resource access controls based on his or her permitted role. Therefore, the end user, for example, can configure computer resources such as disks, networks, file folder/directory systems, and others. Also, various computer tasks & operations can be executed by the computer application; and the computer operating system of a computer system provides the results of tasks to the end user. Specially, with a generic computer operating system, this computer user work environment allows a plurality of concurrent users each to run multiple concurrent tasks or operations simultaneously.
The computer user work environment has evolved from paper tape & punch card environment, command line environment on a native system to window & mouse click environment on a native system in the past. This invention provides users a web-based computer user work (operating) environment on top of generic operating system for a single or multiple computers, and allows each of the users to access one or multiple computing devices through a conventional web-browser.
The accompanying drawings, which are incorporated into and constitute a part of this specification, illustrate one or more examples of embodiments and, together with the description of example embodiments, serve to explain the principles and implementations of the embodiments.
In the drawings:
The traditional web server or other server may support a user from a web browser on a computing device somewhere on the network to perform tasks of accessing the server, that the task could get quick response and could be finished in a short period of time, fore example, checking a web server's status or getting the server's other information, et cetera. However, it may not support well for multiple simultaneous concurrent tasks or operations from the same web-browser, especially when these tasks are time consuming to finish.
For example, creating a 60 GB file system on the server, or configuring a raid controller on that server illustrated in
To solve these problems and effectively to support multiple simultaneous concurrent tasks in a web-console for both the simple computing environment as illustrated in
In addition, a user space task list illustrated in
These and other features, aspects and advantages of the present invention will become understood with reference to the following description, appended claims and accompanying figures set forth below.
The CCDSVM, typically in one embodiment illustrated in
When a server provides software support for allowing a web-browser on a computing system (device) such as a desktop, laptop, server, PDA, or cell phone to access and manage the server, this web-browser is often referred as a web-console. With the CCDSVM, a permitted user from the web-console could be able to access and operate the entire CCDSVM.
To simplify the discussion, the term of thread and process are roughly used without differentiation between them in this invention regardless of the very restricted definition of the thread and process in computer science field. Here both thread and process are basically referred as a sequence of instructions based on a piece of program code that starts to be executed by a computer system step by step to carry out a computer task.
Lock is a mechanism that allows a thread to look a computer resource for its own use and prevents other threads from accessing to the same computer resource at the same time. There is conventional lock which can be acquired and released by the same thread. The conventional lock mechanisms have used by most software developer crossing the software industry. The lock described in this invention may or may not be a conventional one. The non-conventional lock mechanisms created in this invention can be acquired by one thread and may be released by same thread or by another thread. Therefore, it is non-conventional lock serving threads on the computing system.
The console host 1, from which a user is able to perform system tasks or operations for the server 3 through the web-console (browser) 8. The console host 1 can be any computing system on the network 2 such as a server, a desktop PC, a laptop PC, a hand held PDA, or a cell phone. The web browser 9 may be commercially available software from any vendor or a proprietary software. The web browser 9 is able to handle web protocol such as HTTP. The console host 1 may also include other software modules 13 that may be implemented with any suitable programming languages such as C, C++, Java, XML, et cetera. Other software modules 13 are used to communicate between the server 3 and the console host 1 using IP, non-IP or any suitable protocols for receiving and/or sending data between the console host 1 and the server 3.
The server 3 could be a web server computer or any kind of computing system configured with web server software that includes web server software 7 and console supporting software 5. The console supporting software 6 includes web server interface 5 and other services software modules 8, where the other services software 8 is operated natively on the server 3. The web server software 4 may be a commercially available software or proprietary software, which is able to accept and handle the web protocol such as HTTP. A native web-console (browser) 9 enables a user to access and operate the server computer 3 locally.
Net 2 represents a network infrastructure such as Internet, intranet, and (LAN). The net 2 includes all kind of related network equipment and media such as switches/routers, and different kind of connecting cables and wireless communication media.
The console host 1 may also include other software modules 13, which may be implemented with any suitable programming languages such as C, C++, Java, XML etc. These software modules 13 may be used to facilitate communications between the control system 2 and the console hosts 1 using IP, non-IP or any suitable protocols for receiving or sending data between the console host 1 and the control system 2. To support a non-web-based networked console, the software configured for the web console 9 shall be capable of handling protocols other than web protocols such as deploying HTTP for communicating with the console supporting software 6 on the control system.
The control system 2 could be any computing system on the network such as a server, a desktop PC, a laptop PC, or others. The control system 2 includes web server software 7 and console supporting software 6. The console supporting software 6 includes web server interface software modules 5 and control management software modules 4. It should be noted that the console supporting software 6 may includes others service software modules. It may also have a native web browser used as a native web-console 9. The web server software 7 discussed earlier could be commercially available software from a major vendor or other proprietary software that is able to accept and handle the web protocol such as HTTP. The web server software 7 sends data to and receives data from the web-console 9 of the console hosts 1.
The console supporting software 6 can be implemented with any suitable languages such as C, C++, Java, XML, etc. or even implemented by using a combination of different languages as long as it provides the features and functionality described in this invention. That means it is language independent. In addition, the communication protocol used between the console support software 6 and the service software modules 8 of the system units 3 could be any suitable protocol such IP based, or non-IP based or other protocols. The console support software (6) communicates and manages one or more system units 3 and collects resource information on the control system 2 and/or one or more system units 3.
There may be several fixed threads being created based on the control management software modules 4, and each fixed threads may create one or multiple child threads for perform one or more multiple tasks. There are may be various number of threads that are created based on the web server interface software modules 5 for supporting each of tasks submitted by a user via operation menu displayed in the web-console 9. All of these threads may be communicated with each other through inter-process communication and are simply referred as the thread of the console supporting software 6. However, to simplify the discussion, they may be just referred as the console supporting software 6 without mentioning the thread at all.
If there is a need to support a less effective non-web-based networked console, there is no need for the web server software 7 and web server interfacing software module 5 being employed. Instead, an additional network software module is required that could be implemented with any suitable programming language and any suitable communication protocol other than web protocol (HTTP). This network software module can communicate with networked console software on the console host 1 across a communication network and can communicate with the rest of the console supporting software 6 via inter-process communication mechanism.
The system unit 3 could be any computing system on the network such as a server, a desktop PC, a laptop PC, a hand held PDA, a cell phone, and any operational system. The server could be a video server, a web server, a storage block data server (SAN unit), a video monitoring device, and so forth without limits. The system unit 3 contains service software modules 8 that are capable of communicating with the outside world. For example, the service modules 8 is used to communicate with the control management software 4 of the control system 2 for carrying out the tasks distributed from the control system 2, or to communicate with the clients 10 of the CCDSVM for delivering services to them, or to communicate with another system unit 3 for transferring the data. The service software modules 8 could be implemented with any suitable programming languages such as C, C++, Java, or others. It should be noted that the communication protocol could be any suitable protocol such as IP (Internet Protocol) base or other non-IP based protocol.
The net1 11 represents any kind of communication links between the control system 2 and the web-console 9 or the client hosts 10. The net1 11 could be an infrastructure of internet, intranet, LAN or others that comprises connection media such as cables of Ethernet, optical Fiber, and/or other, wireless media, bus, and includes communication equipment such as switches, routers, and/or adapters.
The net2 12 also represents a communication infrastructure comprising communication media and equipment that are similar to the net1 11 has, except for providing communication between the control system 2 and the system units 3 or the web-consoles 9 across the infrastructure of internet, intranet, LAN, WAN, or other.
The client systems 10 are not part of the CCDSVM but they may requests services from the CCDSVM as shown in
Data traveling from the console supporting software 6 to the web-console 9 includes two reverse steps. First, the web server software 7 gets the data from the console supporting software 6 via inter-process communication. Second, the web server software 7 sends data to the web-console 9 via the net 11 or 12. To simplify the rest of discussion, this reverse data traveling will refer to as data being sent from the console supporting software 6 to the web-console 9 or refer to as the web-console 9 gets data from the console supporting software 6. In addition, the terms of data, information, and information on a web page will be used interchangeably herein.
The detailed explanation of
In one example, a user A at a web-console 9 receives an authentication from the console supporting software 6. In one embodiment, a successfully login on the control system 2 is considered an authentication because it authorizes the user A to access the CCDSVM. Thereafter, the user A can obtain all necessary information about the system units 3 and the control system 2 received from the console supporting software 6. When the user A initiates a task for a selected target computing system, which is either a system unit 3 or the control system 2, the task information is transmitted via the net 11 or 12 from the web-console 9 to the console support software 6 on the control system 2.
A thread is created based on the console support software, 6 where the thread will serve and carry out this task in background. The created thread acquires a lock and stores the task information into a valid entry of a user space task list shown in
In addition, multiple web-consoles 9 for multiple concurrent users anywhere on the net 11 or 12 also can be supported. The obtained locks for this task will be properly released one at a time along with the task execution up to a point when the task is finally finished. Therefore, each task could be executed without time delay. Also, the stored task information will be removed upon the execution of the task is finished.
If total tasks initiated from the web-console 9 have succeeded the maximum tasks allowed by the console supporting software 6, the initiated task is failed. The locks will be released by the corresponding thread and the user A on the web-console 9 will be notified correspondingly via net.
If an existing task is in a stage of changing a resource object on a target system and if a newly created task will make change on the same resource object on that target system, the newly initiated task may fail or may have to wait until the previous task is finished. Further, if a task is failed, the locks associated with the task will be release by the thread and the user A on the web-console 9 will be notified across the network of 11 or 12 by the console support software 6.
The credential of executing a specific task on a specific target computing system submitted by the user A is checked, where an ordinary users' access & operation permissions and credentials are setup by administrator with supervisor or special privileges. If the user A is not permitted to perform any task on such target computing system or is not permitted to perform such task on any one of the computing systems in the CCDSVM, the task execution will fail and the user A will be notified. Otherwise, the task will be carried out by the corresponding thread on the target computing system that is either a control system 2 or a system unit 3. If there is a need, the console supporting software 6 will send the results or data back to the web-console 9. When the task is failed nor succeeded, the threads of the console supporting software 6 will release the locks acquired for this task.
If the task needs to be executed on the control system 2, the thread created based on the console supporting software 6 will carry out this task. The threads of the console support software 6 also need to determine if they need to create another thread to execute this task. If there is a need, another thread will be created to execute this task. Once the task is finished, the corresponding locks will be released by the console supporting software 6.
If a task needs to be executed on a system unit 3, the console supporting software 6 will transmit the task information via the net2 12 to the service software module 8 of the target system unit 3. The thread based on the service software module 8 of the target system unit 3 will carry out this task. The service software module 8 on the target system unit 3 needs to determine if an additional thread needs to be created in order to execute such task. If there is a need, an additional thread is created to execute this task. Once the task is finished on the target system unit 3, the corresponding status of the task execution is transmitted back to the console supporting software 6 of the control system 2. Upon receiving the task finished status, the locks associated with the thread of the console support software 6 for that task are released.
The Task Issued from Web-Console
The multiple concurrent tasks issued from a web-console 9 by a user could be any of the followings:
a) Move or transmit data such as a multiple gigabytes of file or other data in any form from any point or any computing system to another point or another computing system within the CCDSVM.
b) Configure, partition and assign entire storage system (raid/disk) within the CCDSVM.
c) Setup authentication for a specific user from a web-console on a specific console host with certain privilege for the entire CCDSVM or for a specific computing system, which could be any one of the system units 3 or a control system 2. Setting up the steps of authentication process for any specific services on one or more specific system units 3.
d) Monitor and display activities and status for networks, storages, CPUs, processes and threads in the CCDSVM.
e) Create file system, file and directory structures, and support all other related data file operations on either the control management system 2 or the system units 3.
f) And all other type of tasks and operations that might be run in other operating system (OS) environment.
The capability of providing user with the multiple concurrent simultaneous operations and tasks on the web console 9 has indicated that this invention has created a web-based user work environment on top of an existing operating system of a single computing system or multiple computing systems. Further, this is a consistent working environment for a computing system since it allows a user to access exact the same working environment through the web-console 9, which could be a web browser located either on the computing system or located on other remote systems.
The user-login mechanism is also supported by the console supporting software 6. The web-console 9 obtains a login web page from the console supporting software 6 via the network of 11 & 12. Once the user provides an account name and a password via the login page displayed in the web-console 9, the authentication information is sent to the console supporting software 6 for validation. Upon successful validating the user account and password information, the console support software 6 sends all necessary information such as IP address to the web-console 9, where the information also includes the information of the control system 2 and system units 3.
The Maximum Tasks
The maximum multiple concurrent simultaneous tasks that can be initiated from the web-consoles 9 are determined by the console support software modules 6, and they are also determined based on the needs and the capacity of the control system 2.
The Credential Checking
The credential of a user includes the permission to access all or partial computing systems or a single computing system within the CCDSVM. The credential further includes the permission to run all tasks or partial tasks that are listed in the previous section of “The Task Issued From Web-Console”. It also includes the permission of accessing a specific size of storage volumes. For example, a user B may be granted a permission to run tasks on computing systems X, Y, and Z. Another user C may be granted a permission to run tasks on the entire computing systems in the CCDSVM environment. The user C might be allowed to get system status on the computing systems X, Y, and Z only while the user B may be allowed to run all tasks on the computing systems X, Y, and Z. Each computing system mentioned here could be a control system 2 or any of system units 3. This basically represents a two-level authentication policy and checking. The first level is the security imposed on the control system 2 and the second level is the security imposed on the system units (3 of
The Web-Server Interface Software Modules
The web-server interfacing software module 5 is responsible to get information from or send information to the web server software 7. It also interacts with the control management modules 4 via inter-process communication and communicates with service module 8 of the system unit 3 via the net2 12.
The Control Management Software Modules
The control management modules 4 on the control system 2 are responsible for communicating with the system units 3 for sending data to or receiving data from the system units via the net2 12. It also provides information of the system units 3 to the web interface software modules 5 of the control system 2 via an inter-process communication mechanism.
The Layered CCDSVM Structure
To be more efficiently support multiple concurrent tasks over a larger number of the system units 3, the CCDSVM can be organized into a multi-layered structure as illustrated in
